產品提供形式：

Liquid or Lyophilized powder Warning: in_array() expects parameter 2 to be array, null given in /www/web/cusabio_cn/public_html/caches/caches_template/default/content/show_product_protein.php on line 662
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
緩沖液：

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質期：

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
貨期：

Basically, we can dispatch the products out in 1-3 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
注意事項：

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
產品描述：

The Yeast-expressed Recombinant Escherichia coli (strain K12) Type 1 fimbrin D-mannose specific adhesin (fimH) validated by LC-MS/MS Analysis is a full-length of mature protein containing the amino acid sequence of Phe22-Gln300. Its purity is measured by SDS-PAGE and reaches up to 90%. It has a predicted molecular mass of 29.1 kDa, but its observed molecular weight is slightly higher because of the glycosylation. Animals such as rabbits immunized by this recombinant fimH protein will obtain anti-fimH antibodies.

FimH is the adhesion region of type 1 fimbriae in E.coli. Adhesion fimH contributes to the colonization of Uropathogenic Escherichia coli (UPEC) in the bladder through the binding of its lectin to glycoproteins with terminally exposed mannose, thus causing urinary tract infections (UTI).

功能：

Involved in regulation of length and mediation of adhesion of type 1 fimbriae (but not necessary for the production of fimbriae). Adhesin responsible for the binding to D-mannose. It is laterally positioned at intervals in the structure of the type 1 fimbriae. In order to integrate FimH in the fimbriae FimF and FimG are needed.
